"Our plan with Atlas is to eschew the traditional two-betas and then RTM model that we often use with big projects at Microsoft, and instead move to a model where we ship very often (at least once every month and often more frequently then that), get feedback as early as possible, share our ideas out in the open (even when they are not 100% baked), and above all use the broader developer community to make sure we build the right technology. All of the client-library code is shipped as standard .js files that you can read and look over to see what we are doing. Note that we have deliberately not removed white-space, obfuscated, or compressed them down our goal right now is to preserve developer readability (note: when compressed the entire Atlas client library is around a 32k download and cacheable on the client -- although typical scenarios will usually use only a subset of the .js files, so it will be even smaller than that). Please give us your feedback on the forums, tell us what you like and dont like, and how we can build the right product you want to use."
